Fortunately, in California there are no established populations of Brown Recluse Spiders, though legends of their bite and venom abound. Still, it is helpful to know about this notorious spider that could easily be brought into California by commerce or travel.

The brown recluse is about 3/8 of an inch in body length, and has a uniformly colored abdomen that can vary from cream to dark brown depending on diet. It has a dark brown violin shape on the cephalothorax, which is the portion of the body to which the legs are attached. The neck of the violin points toward the abdomen. The main identifying feature that you should look at is the eye pattern consisting of six eyes in pairs with a space separating the pairs. Most spiders have eight eyes in two rows of four. There are no spines on the legs, only fine hairs.
